FILLING-MACHINE.

To all whom z't may concern Be it known that I, CHARLES H. BUCH- HoLz, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State-:of Ohio, have invented certain new and useful Improvements in Filling-Machines; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the saine.

This invention relates to automatic lling machines especially designed for lilling containers with liquids and semi-liquids.

The object of this invention is to provide a filling machine of the class set forth wherein the predetermined amount or quantity of liquid or semi-liquid to be contained or delivered is automatically determined by means of a balance which co-acts with a delivery faucet through intermediate mechanism so as to deliver and determine the amount delivered and to automatically close the faucet at the proper moment, this being accomplished accurately and i, positively, leaving no drip after the valie of the faucet is closed.

A further object of this invention is to so construct the mechanism that a minimum amount of pressure will be as effective as a maximum amount.

This invention consists in the parts and combination of parts, all of which will be 'hereinafter more fully set forth and claimed.

Figure I, is a view in side elevation representing a filling machine constructed according to this invention. In this view certain parts are removed to better disclose the interior or underlying mechanism. This view illustrates the mechanism as adjusted when the valve is open.

Fig. II, is a view in side elevation of the operating mechanism showing the position of the parts when the valve of the faucet is closed.

This invention is an improvement on the invention disclosed in my patent of May 4v, 1915, No. 1,137,836, the improvement being comprised in a more sensitive auxiliary tripping device and mechanism whereby the valve of the faucet is closed.

In carrying out this invention as illustrated in the drawings presented 1 repre- Speciioation of Letters Patent.

this dog 21 bein 4able bracket and Patented J une 11, 1918. Renewed April 13, 1918. Serial No. 228,505.

sents a tank for containing and supplying the material to be proportioned or canned. The tank 1 has, leading from its bottom, a delivery pipe 2 controlled by a cut-oli` valve 3. The outer end of the pipe 2 is lprovided with a valve controlled faucet 4 moves with the arms 8`11. e opening of the valve is accomplished by means o1' a vertically reciprocated rod 15 which ento a foot treadle 17 and the rod b in raised position by means 18, one end of which is 19 which the rod l5 end of said spring being attached to the adjustable collar 19 secured at the lower end of the rod 15. The bracket 19 is secured to a standard 20 upon which the delivery pipe with the actuating mechanism is mounted, thus it will be seen that as the foot treadle 17 is depressed the valve of the faucet is opened and locked open allowing the container C to be filled.

Inasmuch as it is essential that after a predetermined amount of liquid or semiliquid has been poured into the container C the valve should be automatically closed the following described mechanism is provided for this purpose:

4 21 represents a pivoted weighted dog,

pivoted as at 22 to a suiteing held of a spring provided with a suitable` standard 10 attached l weight 23 at its operating end. The Weighted operating end is designed to strike a projecting pin l? on the engaging end of thenveightedilever l2 andfrelease the catch or locking mechanism thus allowing the valve of the faucet to automatically close.

The Weighted dog 21 is raised through the medium ofV an adjustable collarv 24 on the rodl5, the collar 2d engaging the end 21 of the dogL 2l, thus depressing. itL at this end and raising it at its Weighted end, all of whichlis accomplished as` the valve of the, faucet; is opened by the depressing ofr the-treadle 17.

InV ondertovsustainA the Weightedy end of the dogi21Y in its raisedI` position l provide on, its end a .notch N.- Whichr is inv turn` engaged by a slightly over-balanced pavvl 25 inch, is pivotedl, as. at 26 andvv has an oppositely extending arm 2f7, provided with a projectingpin 2S which inturn is adapted toibe engagedby.l the upper end of a rod 29.t ustablyy secured. to the plate 30 i of. the balance, this plate 3Q being. directivbeneath thefaucet 4s. andI adapted to Isustain the container tov be filled'.- Thus asr the plate. 30 becomes A oven-balanced or moves downward thecontainerisfilled or receives its predetermined qtlantitygthe upper end` of the adjustablerodA 29 engagesthe pin 28 pulling the.V arm 2,7i ofthe pavvl 25 downward andldisengaging the, end of the saidy pavvl fronr the netch. N', allowing the Weighted endoftheidogl2l to ,strike the pin P-thus in turn, disengagmg the Weighted lever 12 frein the loWenend of the depending arm land, allowing; the valve ofthe faucetl to immediately Close tightly- Thje balancing. device for determining the amount to be. received by the containers to be=filled maybe of any suitable construction; the `one illustrated being. off the cOllIlter-.balancing-type and having a proportionatelyWeightedqmemben locatedjon the platen opposite to the` plate upon Which the container rests.

nsettingforth thisinvention I. have described: in detail i the construction` illustrated in the. drawingsibut it is apparent both` in structural'detaihandin assemblage and also in location of parts that. changes4 may be madexvithout,` departingwfrom the invention.

Havingthus described myinvention what L Wish tolclaim is:
